Characteristics of Computer

Characteristics of computer means its qualities or features.

Although the computer are of various types depending on their size and capacity but all the computers have some common characteristics.

As you all knows that a computer has a lot of features or characteristics but in all those characteristics 5 are the most popular.

Therefore the five Major characteristics of computers are given below:

  1. Speed
  2. Accuracy
  3. Consistency
  4. Data Storage Capacity
  5. Flexibility

Now let's briefly describe about all the above listed 5 characteristics of computers.


Speed is the first major from all the five major characteristics of computer.

Speed of a computer device is very fast as it can perform in a few seconds, the amount of calculation or anything that we are human being can do in an entire year or more.

2 gigahertz to 4 gigahertz is the speed range of computer device.


Accuracy of a computer is consistent. Computer gives us accurate result or calculation.

Error occurs in result for any calculation in a computer are only due to wrong program or instruction, inaccuracy in input data etc.

You can directly says that errors in computers can happen only due to human beings. Otherwise the accuracy of a computer device is constantly high.


Computer is a consistent machine, it means that computer never gets tired of working more. You can use computer to perform your task without any error for any number of hours, any number of hours means you can use your computer system continuously for 24 hours a day and 365 days a year.

Data storage capacity

Computer can store huge amount of data in a small sized storage disk such as hard disk, CD, DVD, PenDrive, memory card etc.

Let's give you an idea that now a computer can store huge amount of data in a small storage disk. For example a Pen drive of 16 GB is enough to store the entire Encyclopaedia Britannica.

  • See pictures
  • Write textual documents and save
  • Open and read anything
  • and many more

Some More Characteristics of Computer

Here are the list of 3 more common characteristics of a computer system, that are:

  • Versatility
  • Automation
  • Remembrance Power


The computer system is very versatile machine. The most wonderful feature of the activities of different types from simple calculation to the complex scientific operations and computations and is also capable of preparing the examination marks sheets, bills, letters, documents, and also the design and modelling of navigating missiles and satellites.


The word automation is conjoint with the computer for a particular task, the computer does not fully depend on the user, but it proceeds the task in forward direction automatically till its completion.

Computers can be easily programmed to perform a series of task according to the requirements. The computer automatically executes these instructions sequentially, if any error occurs, it produces the appropriate error message.

Remembrance Power

The computer can store and recall the information at any time because of the presence of the secondary storage devices, But this is not possible with the human beings.

Although the brain of human being can store unlimited data.
